Study of microparticle retention and drainage aid system on Pulp and Paper
Abstract: This article introduces the study of microparticle retention and drainage aid system on Pulp and Paper. The experimental results show that Maintain the fiber under the premise of Negative , CPAM unit Retention System and CPAM / bentonite Retention system both can improve the slurry Retention effect,And with the addition of, Retention slurry to enhance the effect of, However, CPAM / bentonite Retention was significantly higher than the effect of the system unit CPAM Retention System. And for the slurry in the near-neutral pH and neutral conditions, Have a good effect of Retention .CPAM / bentonite system, the best dosage CPAM0.1%, Bentonite 0.2-0.3%. And not more than additive, additive effect of the application of the best cases, the surface of copy paper a slight improvement in strength, quantitative, increased thickness, but the paper breaking length of the ring have different compressive strength the extent of the decline in.
